They are right, on my 2011 got $3k, 1.9% for five years (basically free money), GM target incentive, and GM credit card points and lowest supplier discount, ended up being a bit more than $14K off GS Convertible.
In looking at the latest on 2012 discounts looks like my same car would be $5k more (of course main problem is no JSB and not much selection of other colors either).
Guess for once my timing is right on buying something
